The paper deals with the flat roof of low-energy buildings. The building sector is currently focusing on the maximum energy efficiency of buildings and related energy savings. At present, the building sector holds more than 40% of energy consumption and 36% production of greenhouse gas emissions. The whole sector of buildings uses more than 50% of the Earth's raw materials and produces approximately 50% of world waste. Roofs occupy about 20?25% of urban surfaces. The green construction practice expands and complem...

The contribution deals with the energy performance of variants of the building with the glazed cladding. Nowadays, glass facades on commercial buildings are a big fashion hit. Correct adjustment of the glazed surfaces helps us to warm the interior in the cold months, but in the summer months, the interior space becomes overheated. These buildings then look truly original, modern and architecturally interesting. The paper offers possibilities of the structural design of facade shielding and compares the results of ...

The urban area has noticeably higher temperatures than other areas located in the undeveloped area. This is due to the overlapping of large areas of the original vegetation with the construction of buildings and roads. Concrete and asphalt surfaces absorb a large amount of heat from the sun that radiates back into the environment. The impact of ever-expanding urban arrest increases the intensity of so-called thermal islands, and life in some cities becomes difficult in the summer months. Due to the absence of gree...

The paper deals with the effective management of rainwater. Given the current climate change, which is currently faster than anticipated, environmental issues are very timely. These sudden changes are mainly caused by human activity. The most noticeable climate change is the increase in temperature and changes in the rainfall regime. These two changes are closely linked. The average consumption of drinking water per capita is over 100 liters of water per day in civilized advanced nations. But about 50% of this con...

Volatile organic compounds (VOCs) play an important role in the IAQ evaluation process. Chemical contaminants emitted by dry building material and indoor equipment influence long-term indoor air quality. VOCs adversely affect both occupant comfort, productivity and health. Most of the health hazards related to VOCs emissions occur during the first months of occupation or after refurbishing the building. At present, most people generally spend up to 90% of their daily time in the indoor environment. Humans spend al...
